WebSep 29, 2014 · K has a more exothermic electron affinity because the electron gained fills the 4s orbital. In Ca the electron goes to 3d. The energy gap between 4s and 3d is enough to make the process barely exothermic. Note that the numbers given in tables are positive but that the process is exothermic. Share Improve this answer Follow WebNov 26, 2024 · Superhalogens are molecules that have electron affinities (EA) greater than that of Cl, the element with the highest EA (3.62 eV). It is well known that noble gases have closed electronic shell structure and hence have high ionization potentials and low electron affinities, due to which they are chemically inert and resistant to salt formation ... egyptian ethiopian war
Difference Between Electronegativity and Electron Affinity
WebThe greater the distance, the less the attraction and so the less energy is released as electron affinity. Note: Comparing fluorine and chlorine isn't ideal, because fluorine breaks the trend in the group. However, comparing chlorine and bromine, say, makes things seem more difficult because of the more complicated electronic structures ... WebNov 20, 2024 · Electron affinity can be either positive or negative value. The greater the negative value, the more stable the anion is. Although affinity varies greatly across the periodic table, some patterns emerge. Generally, the elements on the right side of the periodic table will have large negative electron affinity. WebMay 7, 2024 · The greater the effective nuclear charge the more tightly an electron is held in by the nucleus because there is less electron shield between the valence electrons and the nucleus, and so, the smaller the … egyptian exhibit
